How should you set up your notes when using the Cornell method?
0 with pictures and maps
0 with levels and sublevels
0 with right and left sides
0 with tables and charts
Answer:
With right and left side charts
Explanation:
I was doing research on this exact question, so here is what I have been looking at;
The Cornell method uses a two-column approach. The left column takes up no more than a third of the page and is often referred to as the “cue” or “recall” column. The right column (about two-thirds of the page) is used for taking notes using any of the methods described above or a combination of them. After class or completing the reading, review your notes and write the key ideas and concepts or questions in the left column. You may also include a summary box at the bottom of the page, in which to write a summary of the class or reading in your own words.
Answer:
with right and left sides

When should the shop ventilation fan be turned on?
Answer:
When cars are running
Explanation:
The shop ventilation fan should be turned on when there are smells, dampness, smoke, and other contaminants in the shop environment. Also, when there is excessive temperature and moisture it should be turned on.
What is Ventilation?
Ventilation assists in cooling your attic by pushing away suffocating hot air from within and bringing in cool air from outside. This keeps hot air from entering your home and raises the temperature in your living area, reducing the strain on your air conditioner.
Exhaust fans purify the air by eliminating smells, dampness, smoke, and other contaminants. Also, it avoids Mold that may grow when there is steam and moisture in the air.
Hence, The shop ventilation fan should be turned on when there are smells, dampness, smoke, and other contaminants in the shop environment. Also, when there is excessive temperature and moisture it should be turned on.

Lyndon is investigating whether putting plastic on her windows will help seal out cold winter drafts. She covers a window on the south side of her house with plastic and measures the inside temperature near the window. She also measures the inside temperature near a window without plastic on the north side of her house. The windows are the same size and design. Why is this not an ideal controlled investigation?
A.
The windows should be different sizes to introduce variation.
B.
The drafts at each window may be different because the windows aren’t near each other.
C.
Temperature isn’t a good indicator of cold winter drafts.
D.
Outside temperature is a better indicator of cold winter drafts than inside temperature.
E.
The type of plastic used in the investigation isn’t mentioned.

How many grams of water at 5.00 °C would we need to mix with 140.0 g of water at 85.0 °C to obtain a final temperature of 43.0 °C ?
Answer:
We need 154.737 grams of water at 5 ºC to obtain a final temperature of 43 ºC.
Explanation:
From Thermodynamics we know that mixing processes involve the interaction of substance at different temperatures so that thermal equilibrium is reached by cooling down the substance with highest temperature and heating up the subtance with lowest temperature.
Let suppose that mixing occurs at steady state, that is, that system does not have energy interactions with surroundings. According to the First Law of Thermodynamics, we get that energy interactions are represented by:
[tex]H_{L} + H_{H} -H_{R} = 0[/tex]
[tex]H_{L} + H_{H} = H_{R}[/tex] (Eq. 1)
Where:
[tex]H_{L}[/tex] - Enthalpy of cold water, measured in joules.
[tex]H_{H}[/tex] - Enthalpy of hot water, measured in joules.
[tex]H_{R}[/tex] - Enthalpy of mixed water, measured in joules.
Since there are no phase changes, we can expand formula by using the definition of sensible heat. That is:
[tex]m_{L}\cdot c_{w}\cdot T_{L}+m_{H}\cdot c_{w}\cdot T_{H} = m_{R}\cdot c_{w}\cdot T_{R}[/tex]
[tex]m_{L}\cdot T_{L}+m_{H}\cdot T_{H} = m_{R}\cdot T_{R}[/tex] (Eq. 2)
Where:
[tex]m_{L}[/tex], [tex]m_{H}[/tex], [tex]m_{R}[/tex] - Masses of cold, hot and mixed water, measured in grams.
[tex]c_{w}[/tex] - Specific heat of water, measured in joules per gram-Celsius.
[tex]T_{L}[/tex], [tex]T_{H}[/tex], [tex]T_{R}[/tex] - Temperatures of cold, hot and mixed water, measured in Celsius.
But we know from Principle of Mass Conservation that:
[tex]m_{R} = m_{L}+m_{H}[/tex] (Eq. 3)
Then, we simplify (Eq. 2) and clear the mass of cold water:
[tex]m_{L}\cdot T_{L}+m_{H}\cdot T_{H} = (m_{L}+m_{H})\cdot T_{R}[/tex]
[tex]m_{H}\cdot (T_{H}-T_{R}) = m_{L}\cdot (T_{R}-T_{L})[/tex]
[tex]m_{L} = m_{H}\cdot \left(\frac{T_{H}-T_{R}}{T_{R}-T_{L}} \right)[/tex] (Eq. 4)
If we know that [tex]m_{H} = 140\,g[/tex], [tex]T_{L} = 5\,^{\circ}C[/tex], [tex]T_{R} = 43\,^{\circ}C[/tex] and [tex]T_{H} = 85\,^{\circ}C[/tex], the mass of cold water needed to obtain a final temperature is:
[tex]m_{L} = (140\,g)\cdot \left(\frac{85\,^{\circ}C-43\,^{\circ}C}{43\,^{\circ}C-5\,^{\circ}C} \right)[/tex]
[tex]m_{L} = 154.737\,g[/tex]
We need 154.737 grams of water at 5 ºC to obtain a final temperature of 43 ºC.

Reducing waste in a shop doesn't help eliminate safety hazards for
employees.
A True
B. False
Pleasseeee help
Answer:
False
Explanation:
Waste in the shop such as garbage, can cause air pollution, which causes various respiratory diseases and other adverse health effects on employees, as contaminants are inhaled and absorbed from lungs into other parts of the body.
These toxic substances in air contaminated by waste that are inhaled by employees include carbon dioxide, nitrous oxide and methane.
Thus, reducing waste which constitutes toxic substances helps to eliminate safety hazards for employees.

How are angular cuts made on a horizontal bandsaw
Group of answer choices
Turning the blade guides to the desired angel
Angular cuts cannot be made on this saw
Holding the workpiece higher on one end than the other
Swiveling the vise to the desired angel
Answer:
A. Turning the blade guides to the desired angel
Explanation:
In a horizontal bandsaw, the user moves the blade to sweep an arc from a fixed cutting plane that will produced repeated number of fixed angle cuts.
Using horizontal bandsaw, only straight cuts at a fixed angle can be attained.
Fixed angle cuts can be made from a horizontal bandsaw thus answer choice B is incorrect.
While using the horizontal bandsaw, the work piece is held stationary while the blade slides on the rollers. Thus answer choice C is incorrect.
The material is normally held with claps to a stationary position before a cut is made by the blade that that repeatedly attains cuts at fixed angle. The vise is not involved. Answer choice D is incorrect.
